sErARABLn FASTENER.

Application filed November 12, 1906. Seriai No. 342,975.

To all whom it may concern:

Be it known that, a citizen of the United States, residing at Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Separable Fasteners, of which the following is a full, clear, and exact specification.

This invention relates to separable fastenersand more particularly has reference to improvements in the type of fastener shown in Patent No. 788,317, dated April 25, 1905, whereby the operation is rendered more certain and effective, the liability of getting out of order reduced, and the adaptability increased.

' The object of this invention is to provide means whereby catching of the hooks in the slider by reason of twisting of the chain will be automatically prevented, and furthermore to improve the slider construction so that it will be stronger and more rigid.

and capable of being more cheaply manufactured.

A further object of provide a fastener capable of application to closures which must completely separate at both ends, instead of at one end only, as has heretofore been proposed. By means of this improvement, the fastener can be applied to' a variety of new purposes to which it has heretofore not been applicable by reason of not being separable at both ends. In the present application, two means of carry ng out this feature of the invention are shown, one havin one chain detachably. secured to the other 1n such manner that it can be pulled through the slider, when detached, and the other having the chains separably secured together, in combination with a shder which is itself separable, when t is deslred to completely open the closure.

The foregoing, and other objects and advantages of the invention will more fully appear hereinafter in connection with the description of the accompanying drawings, W; herem' Figure 1, shows a fastener adapted for closures opening at one end'only, and em bodying the invention; Fig. 2 shows a portion of a fastener wherein the chains are separable; Fig. 3 is a view showing the M tb be separated; Fig. 4 is a ."detall view,"in section of Fig. 2; Fig. 5

is a detail of a latch device, shown in Fig. 2; Fi 6 is a view of a blank for the slider; Fig. 7 is a section of the slider Fig. 1; Fig. 8 is a view of a fastener having the slider and chain both separable; Fig. .9 is a side view of the slider; and Fig. 10 is a view of a modified construction of separable slider.

Referring first to represent two flexible chains adapted to be secured to a garment or other device and links 3,4, a slider5, a top stop 6 and a bottom stop 7. The structure of the chains and of the links is similar to that described in the patent aforesaid. That is to say, each chain specifically.comprises a continuous tape or stringer having a corded edge on which the links, consisting of channel-shaped pieces of metal are clamped by pressure, but it will be understood that this invention is'not restricted to a chain of any particular character or material, nor to any particular character of link. In practice, the hook links 3 will be mounted on one chain, as 1', and the eye links 4: on the other chain, as 2 and interlocking edgewise, so that one looks the adjacent one.

In actual use of the fastener shown in' the patent aforesaid, it is not always possible to prevent twisting of the hook carryingchain, in operating the slider, and frequently it has happened that the hooks caught, and were either bent or broken, and the cause of the difficulty was not easily discoverable by an unskilled user. To over-- come this 'obj ecti on, so as to render the device usable without particular knowledge or manipulation, I have devised means for automatically straightening the chains as they enter the slider and rendering it impossible for the hooks to become entangled in the slider and also insuring accurate interlocking of the two chains. A further improvement consists in constructing a rigid slider which will not be liable to distortion when in practical use. In Figs. 1, 6 and 7 the slider is made from the sheet metal blank shown in Fig. 6, having the neck portion 9-, the wings 10, and the grooves 11, 12, respectively, which, over form the channels for the chains 1, 2, respectively. In order to rigidly secure the two win s when doubled over a shouldered Figs. 1, 6 and 7, 1, 2,

or the slider bent when the blank is doubled rivet 13 is passed through the holes'14 the points will 'matically wings and the ends of the rivet headed down on a washer 15, thereby securing the two the hooks pass into'the' slider, the outer end of the channel 11 is slightly flared, and the" wings adjacent the channel formed with a curved edge, as] at 17, so that if the chain be twisted to bl 'in the entering hook outside the plane of t eslider, it will be automatically turned .by this curved edge in entering so that the hook will not catch.

This' is accomplished partly by the flare and 'partly by the rounded corner 18 striking the hook. By this turning or cam action of the slider on the entering hook link, it is implane. .With eyes there is possible to catch the hook in the slider. After the hook has once entered properly'it cannot thereafter turn out no tendency to catch on the slider, and if each chain carries both hooks and eyes, both sides of the slider will be provided with the cam edges. 6 is a stop button which is placed on one orboth of the chains toprevent the slider from running off-the upper end of the chains, and 7 1s a bottom .stop which also secures the chains together at the lower end. This stop 7 in Fig. 1 consists of a plate having prongs which are-bent down on the tapes, and has an outwardly projectingstop shoulder 21 which Ltheslider strikes at the end of the unalone are separable,

, tape swells, thus firmly locking movement. A feature of improvement in the hook itselfresides in providing the perforation 16 in the channel portion, having sharp edges, into which the corded from moving on the tape, and wlthout any tendency-to cut the tape.

In order to auto-Q of the engaging preventing the hookslider when the chains are to be coupled. To hold the chain 1 in the stop plate 23, there is a latch 26 pivoted on plate 23 and passing through a slot 29. The latch 26 is similar to a hook, a'ndwhen swung to the dotted position permits the lug 27 to be withdrawn through the slot 28 in plate 23. When the latch is turned down, .as in Fig. 2, the lug is held and thereby the chain, against wit-hdrawal. The plate 23 sheet of metal riveted together and has channels 30 in which the end of chain 2 is clamped, and also ',the article. g

The slider is made in two parts 35, 36, having registering projections, and locked by a sliding hook 38 carried by part 36 between the front and back, and engaging-a cross lug 39," 40 being a similar lug acting' as a stop. The hookis operated by grasping the projecting end and releasing aspr'ing 41 from a lug 42 on the'shank'of the latter can be pushed down to clear lu slider is riveted as at 43, and it will be seen that whenthe slider is in its up er position, the two halves of the slider wl'l'be pulled together by the cam action of thehooks and spring latch 41 is released. In Fig. 10, the two halves 35, 36 interlock, as before described, but the hook 45'is pivoted on one part as at 46 and other part. The locking is accomplished by a p1voted locker 48, which canbe' turned into a vertical position to engage'in the notch 49 formed where the two halves of the slider meet. When the locker is turned hooks to. be swung to dotted position to disengage. Also, the curved end of the locker 48 (which also acts as a pull) is slightly eccentric, so that when in vertical position it frictionally engages the notch 49, similarly to a cam, thereby preventing acci-. dental displacement. rable slider constructions, it will be seen that the locking devices, the plates of each practically invisible jury. a
